Exporting data from a map that uses the new 2021.4 Multiple Data Sources feature

[mac471]

I have a map that uses the new "multiple data sources" feature in Tableau 2021.4. When I use Export All, the extension includes rows from all of the data sources used in the map. By definition, since I have multiple, separate data sources (not blended), there's no point to exporting fields across data sources - as those fields would be blank. And you would just get a lot of blank rows in the resulting Excel file.

I realize multiple data sources is a new feature that was just introduced. It seems to me that the user should be able to select the "map layers" on a map worksheet (or the underlying data sources) similar to how you select the worksheets on the dashboard to serve as data sources to export. These map layers/data sources would be sub-selections for a given dashboard worksheet.

This is a really helpful tool. I'm hoping it will be updated to support the new multiple data sources mapping feature.
